SPECIFICATION forming part of Letters Patent No. 291,983, dated January 15, 1884.

' Application filed December 3,1883. (No model.)

To all whom it may concern..-

Be it known that I, HUBBARD O. CHESTER, of Noank, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Anchors, of

which the following is a specification.

The object of my invention is to so construct an anchor that it may, when not required for use, be folded up into compact form.

To this end the invention is mainly characterized by the combination, with a shank jointed or hinged in such manner that it may fold over upon itself, of a stock jointed to the upper section of the shank, and adapted to fold upwardly or in the direction of the prolongation of the shank. By this means, when the shank and the stock are folded, I am enabled to bring the two alongside of one another. In connection with the shank and stock thus arranged I employ independent pivoted orhinged arms, which can be folded up against the shank;

and I also make use of a slide mounted on the shank, and adapted to maintain the arms in their extended or unfolded condition.

To enable others skilled in the art to understand and use my invention, I now proceed to describe more particularly the manner in which the same is or may be carried into effect by reference to the accompanying drawings, in which Figure 1 is a view of the anchor unfolded. Fig. 2 is a view of the same folded.

The shank of the anchor is made in two parts or sections, A B, which are hinged together by suitable means, consisting in this instance of a joint-block, a, received in slots in the contiguous ends of the shank-sections, and connected to the respective sections by pivot-pins b c. The upper section, B, carries the stock C, whose independently pivoted parts are hinged thereto at d in such manner that they fold together upwardly, or in the direction of the prolongation of the shank. WVhen unfolded, they are held in line with one another by the hinge shoulders e, which bring up against like shoulders on the shank. WVhen V the stock is folded and the shank is folded upon itself, the parts will lie snugly and compactly side by side, as indicated in Fig. 2, the length of the lower shank-section, A, being equal to that of the upper section and folded stock combined. The arms D, which are pro vided, asusual, with palms or flukes, are independently hinged or pivoted to the lower end of the shank, as shown, their hinges being substantially like those which hold the stock in place. WVhen folded up, they lie closely against the shank, and when opened they can be held in that position by means of a slide, E, on the shank, which is pushed down until projeotionsf, with which it is provided, bear against the butts of the hinges and against the arms as well.

Folding anchor-arms, combined with a slide for holding the arms extended or unfolded, are not claimed, broadly, by me.

Vhat I do claim herein as new and of my own invention is 1. The combination of the shank, jointed so that it may fold upon itself, with an upwardlyfolding stock jointed to the upper section of the shank, substantially as hereinbefore set forth.

2. The combination of the shank, jointed so that it may fold upon itself, with an upwardlyfolding stock jointed to the upper shank-section, and folding arms hinged to the lower shanksection, substantially as hereinbefore set forth.

3. The combination, substantially as hereinbefore set forth, of the two -part folding shank, the upwardly-folding stock jointed to the upper shank section, the folding arms hinged to the lower shank-section, and the slide.

In testimony whereof I have hereunto set my hand this 31st day of October, A. D. 1883.
